Bacteria present in digestive tract used for |
|
Answer» Answer: Enzymes produced by intestinal bacteria are important in the metabolism of several vitamins. The intestinal microflora synthesizes vitamin K, which is a necessary cofactor in the production of prothrombin and other blood clotting factors. Treatment with antibiotics, PARTICULARLY in individuals eating a diet low in vitamin K, can result in low plasma prothrombin levels and a tendency to bleed. Intestinal bacteria also synthesize biotin, vitamin B12, folic acid, and thiamine. The intestinal flora is capable of fermenting INDIGESTIBLE carbohydrates (dietary fiber) to short-chain fatty acids such as acetate, propionate, and butyrate. The major source of such fermentable carbohydrate in the human colon is plant cell wall polysaccharides such as pectins, cellulose, and hemicellulose. The acids produced from these fiber substrates by bacteria can be an important energy source for the host. Some people are deficient in intestinal lactase, the mucosal enzyme responsible for HYDROLYZING the disaccharide lactose in milk. In these individuals, lactose is not adequately DIGESTED and absorbed in the intestine. Lactose that reaches the large bowel UNDERGOES vigorous bacterial fermentation. The result can be distention, flatus, and diarrhea. Explanation: |

Answer» Answer: When we talk about climate change, we talk about CHANGES in long-term averages of daily weather. Today, children always hear stories from their PARENTS and grandparents about how snow was always piled up to their waists as they trudged off to school. Children today in most AREAS of the country haven't EXPERIENCED those kinds of dreadful snow-packed winters, EXCEPT for the Northeastern U.S. in January 2005. The change in recent winter snows indicate that the climate has changed since their parents were young. |

Illustration below is a dna segment which constitutes a gene. 1. Identify the shaded and unshaded region2. Explain how these genes are expressed. 3. How is the gene different from prokaryotic gene in its expression. |
|
Answer» Answer: The DNA replicase of bacteriophage T4 is a loosely assembled multiprotein complex that is comparable in composition to the replicases of bacteria and humans (15, 20, 26). Among its components are a DNA polymerase (gp43), product of phage gene 43, a sliding clamp (gp45), a clamp loader (gp44/62 complex), a single-stranded DNA-binding protein (Ssb, gp32), a primase (gp61)-helicase (gp41) complex, a helicase-primase assembly factor (gp59), RNase H (gprnh), DNA ligase (gp30), and probably other proteins. The sliding clamp in the T4 replicase is a gp45 trimer, and the clamp loader is a heteromeric complex consisting of four gp44 subunits and one gp62 subunit that are tightly bound together (11). In addition to their essential roles as accessory proteins to DNA polymerase, gp45 and the gp44/62 complex interact with the T4-modified transcriptional machinery of the Escherichia coli host and are required for the COUPLING of phage DNA replication to transcription during the late STAGES of phage development (28, 36). Gene expression is the process by which the instructions in our DNA are CONVERTED into a FUNCTIONAL product, such as a protein. It acts as both an on/off SWITCH to control when proteins are made and also a volume control that increases or decreases the amount of proteins made. When more protein is required, more transcription occurs. Therefore, in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. ... In eukaryotic cells, the DNA is contained inside the cell's nucleus and there it is transcribed into RNA. |

How does haemoglobin help in the transport of carbon dioxide (Co2)????????? |
|
Answer» Answer: CARBON dioxide can bind to plasma PROTEINS or can enter RED blood cells and bind to hemoglobin. This form transports about 10 percent of the carbon dioxide. When carbon dioxide binds to hemoglobin, a molecule called carbaminohemoglobin is FORMED. ... In this SYSTEM, carbon dioxide diffuses into the red blood cells. |

Moulting is controlled by (a) Steroid hormone (b) Amino acid derivative (c) Protein hormone (d) Polypeptide hormone |

Answer» Explanation: The Endocrine System: Hormones An animal’s endocrine system controls body processes through the production, secretion, and regulation of hormones. Hormones serve as chemical “messengers” that function in cellular and organ activity to maintain the body’s homeostasis. Maintaining homeostasis within the body requires the COORDINATION of many different systems and organs. Communication between neighboring cells and between cells and tissues in distant PARTS of the body occurs through the release of hormones into body fluids (usually blood), which carry them to their TARGET cells. Target cells, those having a receptor for a signal, respond to a hormone when they express a specific receptor for that hormone. Cellular recipients of a particular hormonal signal may be one of several cell types that reside within a number of different tissues, as is the case for insulin, which triggers a diverse range of systemic physiological effects. Different tissue types may also respond differently to the same hormonal signal. By releasing hormones, the endocrine system plays a role in growth, metabolism, and sexual development. Hormones also play a role in induction or suppression of cell DEATH, activation or inhibition of the immune system, mood swings, and hunger cravings. In humans, common endocrine system diseases include thyroid disease and diabetes mellitus. Examples of endocrine glands include the adrenal glands, which produce hormones, such as epinephrine and norepinephrine that regulate responses to stress, and the thyroid gland, which produces thyroid hormones that regulate metabolic rates. In organisms that undergo metamorphosis, the PROCESS is controlled by the endocrine system. The transformation from tadpole to frog, for example, is complex and nuanced to adapt to specific environments and ecological circumstances. |
